How can JSON data be effectively decoded and manipulated in PHP, considering the structure of the data?

When working with JSON data in PHP, you can effectively decode and manipulate it using the built-in functions json_decode() and json_encode(). Once the JSON data is decoded into a PHP array or object, you can easily access and manipulate the data as needed. Remember to handle errors that may occur during decoding to ensure the data is valid. 

// Sample JSON data
$jsonData = '{"name": "John", "age": 30, "city": "New York"}';

// Decode the JSON data into a PHP associative array
$data = json_decode($jsonData, true);

// Check if decoding was successful
if ($data === null) {
    // Handle decoding error
    die("Error decoding JSON data");
}

// Access and manipulate the decoded data
echo "Name: " . $data['name'] . "<br>";
echo "Age: " . $data['age'] . "<br>";
echo "City: " . $data['city'];
